Having just bought the X8 to replace my Nokia 5800xm, I wasn't amused that I had complaints from friends on the other end of the phone complaining of a loud background noise. It's seems that this is a known problem across other Xperia handsets and even other android phones. Is there anything that can be done to fix this problem, am getting a replacement tomorrow, but am guessing it will happen on that too . Not a good start changing from symbian to android!!!
